Description
Advance Headers High-Performance Mild Steel Exhaust Extractors for Nissan Skyline R31 & RB30 3.0L SOHC Inline 6-Cylinder Engines (1986–1991)
The Advance Headers Performance Exhaust Extractors (A217) are heavy-duty mild steel tubular manifolds custom-engineered explicitly for the iconic late-80s generation of the Nissan Skyline and cross-platform muscle setups. Tailored precisely to fit the highly robust, legendary Nissan 3.0-Litre (RB30E) Single Overhead Cam (SOHC) inline 6-cylinder engine housed within the R31 Skyline chassis—as well as the immensely popular Australian Holden VL Commodore platform applications—this rugged upgrade replaces the highly restrictive factory cast iron manifold structure. By dropping heavy engine backpressure and optimizing exhaust gas scavenging velocity, it unlocks vital low-to-mid range torque, sharpens throttle response, and delivers a clean, aggressive Aussie RB engine roar.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel 6-Cylinder Performance RB30 SOHC Extractor Assembly
Key Features:
- Heavy-duty mild steel construction structurally built to handle intense under-bonnet thermal expansion cycles and signature high-rpm inline-6 harmonics safely
- Precision-mapped layout engineered to clear factory brake boosters, steering column universal joints, and inner strut towers seamlessly across both R31 and VL chassis formats
- Tuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity and removing heavy factory casting bottlenecks
- Substantially optimizes low-to-mid range working torque delivery—ideal for improving street throttle crispness, everyday cruising manners, and sports-tuned profiles
- Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion, thermal warping, and high-pressure gas leaks
- Engineered for an exceptionally fast workshop turnaround, featuring an estimated baseline installation window of just 1 hour

⚠️ Crucial Induction Setup & Variant Alignment Warnings:
1. Strictly Naturally Aspirated (Non-Turbo) Models Only: This product (Part No. A217) is designed and space-mapped exclusively for the naturally aspirated RB30E engine family. It will NOT fit factory Turbocharged models (RB30ET found in Skyline GTS or Commodore VL Turbo runs) due to entirely distinct primary pipe orientations and the lack of a turbocharger mounting flange placement.
2. Cam and Head Configuration: Flange-mapped explicitly to align with the standard Single Cam (SOHC) 12-valve head architecture. This will NOT bolt onto twin-cam (DOHC) conversions such as RB25, RB26, or custom RB25/30 twin-cam hybrids without custom flange modification.
Please Note: Professional installation by an exhaust specialist or qualified automotive mechanic is highly recommended to guarantee proper system alignment, optimal under-bonnet routing checkouts, and a perfect leak-free seal.
